Radiator for LS and LT Swaps in 1991-1996 B-Body Impala Caprice Roadmaster
For LS or LT engine swaps into a 1991 to 1996 Impala automatic, reliable thermal management depends on a radiator engineered for the B Body frame rails and automatic transmission plumbing. Forged from TIG welded aluminum tanks and a high efficiency core, this radiator mounts to OE brackets without trimming shrouds or fabricating adapters. Equipped with dual electric fans, it delivers airflow at idle and in stop and go conditions to prevent heat soak and hotspots. Core flow paths and hose port positions match factory dimensions for Impala Caprice and Buick Roadmaster models, making installation timely and precise.
Precision TIG Welding for Superior Durability
Every joint in this unit is assembled using precision TIG welding to fuse the aluminum tanks and core plates into a seamless structure. The technique produces weld beads free of contaminants, protecting against leaks under the stress of vibration and heat cycles typical of LS or LT engine swaps. With aluminum's natural ability to dissipate heat, the core sheds engine temperatures rapidly. This approach delivers a lightweight yet robust assembly that remains corrosion resistant and dependable over extended use. This radiator is produced locally to maintain tight quality standards.
Dual Electric Fans for Steady Under Hood Airflow
Equipped with two high capacity electric fans, the system maintains airflow at idle and during slow city driving, preventing heat soak around the engine block. The fans are preinstalled and wired for a plug and play connection, eliminating extra harness fabrication. By drawing air on demand, they reduce reliance on a belt driven fan and free up engine power. This rapid response design keeps coolant temperatures stable under load or while towing. This ensures consistent performance without additional control modules.
Tailored Fitment for 1991 through 1996 B Body Frames
Designed exclusively for 1991 through 1996 Chevrolet Impala, Caprice, and Buick Roadmaster models with automatic transmission, this radiator drops into place using original frame brackets. Hose port positions and shroud clearances match factory dimensions, so there is no need for trimming or custom adapters. Fit accuracy accelerates installation times and reduces potential for misaligned coolant flow paths that can cause hotspots. Installers benefit from a predictable setup that cuts labor hours and limits unexpected modifications. Each unit undergoes inspection to maintain uniform consistency across production.
Bare Aluminum or Black Epoxy Finish for Corrosion Resistance
Select a bare aluminum finish to maximize heat transfer and display its natural metallic sheen, or choose a black epoxy coating for enhanced protection against moisture and road debris. The epoxy is applied under controlled conditions to ensure even coverage and strong adhesion that withstands repeated thermal cycles. Both options preserve core efficiency and extend service life by guarding against corrosion. The choice lets builders tailor appearance and durability to match vehicle style and operating demands.
